In another embodiment, the monitoring process may further set a start time of the particular root cause event as the start time of the new virtual page.

Techniques are described herein for early pruning of potential graph query results. Specifically, based on determining that property values of a path through graph data cannot affect results of a query, the path is pruned from a set of potential query solutions prior to fully exploring the path. Early solution pruning is performed on prunable queries that project prunable functions including MIN, MAX, SUM, and DISTINCT, the results of which are not tied to a number of paths explored for query execution. A database system implements early solution pruning for a prunable query based on intermediate results maintained for the query during query execution. Specifically, when a system determines that property values of a given potential solution path cannot affect the query results reflected in intermediate results maintained for the query, the path is discarded from the set of possible query solutions without further exploration of the path.

The enriched populations can be further modified by the administration of an immunogen to the DC. The DC will take up and process the immunogen on its cell surface.

Complexation of metal ions using chelating agents within a subterranean formation can often be desirable, such as to temper the formation of metal-containing precipitates. However, many chelating agents are produced commercially in an alkali metal salt form that may not be entirely suitable for use downhole, particularly in subterranean formations containing a siliceous material. The working pH range of some types of chelating agents may also be limiting. Treatment fluids comprising an aqueous carrier fluid having an acidic pH, a sulfonated iminodialkanoic acid, and ammonium ions may at least partially address downhole precipitation issues, while providing further advantages as well. Methods for forming sulfonated iminodialkanoic acids can comprise reacting an iminodialkylnitrile with a sultone under acidic conditions to form a fluid comprising a sulfonated iminodialkanoic acid and ammonium ions.
